PRESSURE-RELEASE son CLotrims WRINGrEts To all 't0/1,0m t may concern.'

Be it known that I, JOHN F. HEMENWAY, a citizen ofthe United States,residing` at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in PressureReleases for Clothes IVringers, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a combined automatic and manual pressurerelease for clothes wringers, the object being to provide a releasewhich is so constructed that the same can be readily installed on theordinary construction of clothes wringers now in use.

Another object of my invention is to provide a pressure release in whichthe automatic releasing bars are disposed on theinside of the frameabove the shaft of the upper pressure roll in such a manner that theyare operated by the upward movement so as to release the pressureretaining means on the abnormal separation of the rolls.

Another object of my invention is to provide a clothes wringer havingpivoted latches for holding the pressure'means in predeterminedposition7 said latches having a connection with the manually operatedmeans and the automatically operated means in order to allow the latchesto be moved in position to release the pressure means by the manuallyoperated means in case the automaticl means fails to operate.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings,

Figure 1 is a side elevation of a clothes wringer partly in sectionshowingthe application of my improved construction of pressure releasethereto;

Fig. 2 is a perspective view of a portion of the pressure releasingmechanism detached; and

Fig. 3 is a detail elevation partly in section.

LikeJ numerals of reference refer to like parts in the several figuresof the dra-wing.

In carrying out my invention I employ a clothes wringer of the ordinaryconstruction having the usual side bars 1 connected together by crossbars 2, the side bars being preferably formed slotted, in the upper endsspecification of Letters Patent APatented Nov. 18, 1919.

Application Vfiled May 9, 1917. Serial No. 167,493.

of which are slidably mounted a top bar 3 providedl with threaded boxesl carrying pressure screws 5.

Mounted in the lower portions of the slotted side bars 1 of the wringerframe are bearings carrying` pressure roll shafts 6 and 7, provided withpressure rolls 6', 7 the bearing of the upper pressure roll beingprovided with spring supports on which are mounted coil pressure springs8 which are engaged by bearing plates 9 carried by a pressure bar 10.The bearing plates 9 are adapted to be engaged by the pressure screwsfor adjusting the tension on the pressure rolls.

Secured to the side bars 1 of the wringer frame are slotted plates 11,provided with bearings 12 in which are pivotallv mounted latches 13adapted to be seated within recesses 11 formed in the ends of the topbar 3 so as to hold said top bar in predetermined position within thewringer frame in order to allow the pressure screws to be adjusted foradjusting the pressure means. The latches 13 are provided with laterallyeX- tendin slotted arms 15 which extend through the slots formed in theplates 11 and through which the pressure screws 5 pass as clearly shownin Fig. 1.

In order to provide means for moving the latches outwardly out ofengagement with the top bar to release the pressure means automatically,I provide a pair of releasing bars 1G`which are slidably mounted onscrews 17 Vcarried by the side bars 1 of the wringer frame and areprovided with forked upper ends 18 which are slidably connected to thearms 15 as shown at 19, saidv releasing bars being adjusted in respectto the shaft 7 of the upper pressure rolls 7 so that the bars will beraised by the passage of an abnormal thickness of goods through thepressure rolls. .as the bars 16 are raised the latches 13 are swungoutwardly on their pivots so as to release the top bar, the movement ofwhich is limited by the arms 15 working in-the slots of the plates 11.As the top bar moves upwardly the pressure on the pressure rolls isreleased, andy it will be seen that by this construction when anabnormal thickness of goods orthe operators fingers are drawn betweenthe pressure rolls, the pressure is instantaneously released.

The top bar of the frame is provided with a centrally disposed bore inwhich is slidably mounted the shank 20, of a push button 21 whichcarries stud pins 22 at its lower end on which are slidably mounted theslotted arms 23 of forked levers 2e which are pivotally mounted inbrackets 25 so that when the push button is forced downwardly, thelevers 24 will be rocked on their pivots. The shank of the push buttonis surrounded b y a coil spring 26 for returning the same to normalposition after it has been depressed.

The free ends of the levers 24k are slidably connected to the free endsoic the arms 15, oic the latches 13, so that when the levers are rockedon their pivots by the downward movement o'l the push button, thelatches will be `thrown outwardly out of contact with the top bar torelease the pressure means. ln the construction herein shown I show theconnection between the pivoted levers 2a and the arms 15 in the form ota loose connection as the free ends ot the levers 211 are provided withforked portions 24k which embrace the rounded end bars 15 ot the slottedarms 15. It is, of course, under stood that the ends ot the arms and thelevers could be bent around the bar 15 so as to form. a positiveconnection between the levers and arms without departing from the spiritot my invention, and l do not wish to limit myself to any particularmanner or' connecting the arms and the latches to the operating levers.

From the foregoing description it will be seen that l have `provided aclothes wringer in which a movably mounted top -bar is held inpredetermined position by pivoted latches having slotted arms extendingaround the pressure screws carried by the top bar and having aconnection with the manually operated means and the autoy lnaticallyoperated means so that the pressure can be released by either ot' saidmeans instantaneously.

l claim:

1. A clothes wringer, comprising a trame having pressure rolls andpressure means for said rolls mounted therein, a top bar movably mountedin said frame having pressure screws for adjusting said pressure means,plates carried by the side bars of said frame, pivoted latches mountedin said plates engaging said top bar for holdingsaid top bar inpredetermined position within said Yframe, said latches being providedwith inwardly projecting` apertured arms through which the pressurescrews extend, and releasing bars arranged on the inner faces of saidside bars slidably connected to the arms of said latches at their upperends,
